I just wish they wouldn't use Unity, I mean, it's free I guess, but it's horribly unoptimized and the code is so messy that even really good computers have a hard time running it. Plus graphically it's really unimpressive. I would much rather they have used Unreal. Or Source. Source is free. As I'm certain they're gonna release this for free, CryEngine would've worked too since that's free for nonprofit releases.
